Product Description

DCS Series Screen Channel Speakers

A built-in tilt to the high-frequency horns on 3- and 4-way systems provides more even convergence with the mid-range pattern, ensuring optimum seating-area coverage.

The Digital Cinema Series (DCS) includes 2-way, 3-way, and 4-way screen channel loudspeakers. It’s a diverse collection, but every model embodies QSC attention to detail in design and construction. The result is the smartest loudspeaker line in cinema, starting with a host of innovations built into our screen channel lines.
DCS Screen Channel Features:

The pan-tilt mechanism for mid-high components makes quick work of assembling and aligning screen channel systems. The assembly is labeled for repeat-ability and features a notched tilt adjustment to maintain vertical alignment.

An exclusive integrated sight that works even after the screen has been installed, CineSight allows fast, accurate aiming without having to remove the driver.

The broad-range mid-frequency driver in 3- and 4-way DCS systems keeps key speech frequencies together for superb dialog intelligibility.

A built-in tilt to the high-frequency horns on 3- and 4-way systems provides more even convergence with the mid-range pattern, ensuring optimum seating-area coverage.

Model-specific DSP presets in our DCP, DXP, DCM, BASIS™ and Q-SYS™ processors optimizing our loudspeakers for great performance right out of the box.

The driver protection and equalization network in our screen channel systems improves reliability by protecting HF drivers against damaging DC or low frequency signals.
